Cancel = refund ticket value
No show = preserve ticket value
If you cancel you pay money to get value of ticket returned. Typically only worthwhile if you haven't commenced travel. If you no show you pay money to preserve the rest of the ticket. So if you no show for first sector (without cancelling first sector) and want to cancel whole ticket you would have to pay both no show fee and cancellation fee.
Thats what I understand anyway.
